An eye-protecting display screen and an anti-blue grating film

Abstract

The invention discloses an eye protecting display screen and an anti-blue ray grid film. The display screen comprises a display layer and a cover glass. The cover glass is adhered to the surface of the display layer through photosynthetic glue. The anti-blue ray grid film is arranged on the surface of the cover glass between the cover glass and the photosynthetic glue and comprises a base layer connected with the cover glass and a plurality of prisms densely distributed on the base layer. A plurality of grid protrusions are spaced on the prisms. By the prisms and the grid protrusions on the same, partial blue ray in light is filtered to reduce permeability rate of the blue ray and avoid damage to the eyes by the blue ray; functions of prismatic lens and astigamatic lens are simultaneously provided, astigamatic effect and concealing ability are excellent, optical taste loss, caused by blue ray filtering, is compensated, and display effect of the display screen is free of affection.

Description

Technical field [0001] The invention relates to a display screen, in particular to an eye protection display screen with an anti-blue grating film. Background technique [0002] Medical research shows that among the visible light emitted by the display screen, the shortest wavelength and the strongest energy is blue light. As the strongest visible light, blue light includes blue, indigo, and violet light. They penetrate the cornea and lens directly into the macula and accelerate The cells in the macula are oxidized, which damages the photoreceptor cells of the retina. [0003] The damaging effect of blue light on the retina is a chain reaction: because A2E has absorption peaks in the ultraviolet and blue regions, both ultraviolet and blue light can excite A2E to release free radical ions, which increases its effect on the retina. The damaging effect of the pigment epithelium causes the atrophy of the retinal pigment epithelium and the death of light-sensitive cells. The function ...

AI Technical Summary

Problems solved by technology

[0004] Therefore, protecting eyes from blue light is one of the urgent issues to be solved in the display industry. At present, the methods used in the market are mainly anti-blue light protection stickers, wearing anti-blue light glasses, or processing blue light devices. These methods will be derived. Some other problems, such as reducing the brightness of the display screen and the sensitivity of screen capture, inconvenient use, color difference, etc.
